Document Type and Number:
Japanese Patent JP4582906
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an accurate and inexpensive dynamic pressure bearing type light deflector which can be easily assembled, and can be easily attached to a casing, without the need for taking measures against vibrations at the user. SOLUTION: In the dynamic pressure bearing type light deflector equipped with a fixed shaft erected on the base or the fixing part, a rotor part freely rotatably supported by the dynamic pressure bearing centering around this fixed shaft, and a stator part which rotationally drives the rotor part, the stator part consists of a stator core which is made of the magnetic material, an insulator which is made of the insulating material and is fitted to the stator core, a coil wound around the insulator, and an approximately cylindrical stator core holder having two or more elastic leg parts integrally formed with the insulator and extended in the direction of the base or the fixing part. The parts near the tip parts of the elastic leg parts are fixed to the predetermined parts of the base or the fixing part.
